275A On/Off Battery Switch, RS-BS275

Equipment Type and Primary Applications

The RS-BS275 is a 275 amp DC battery disconnect switch for isolating battery power during equipment shutdown, storage, and safety servicing. Its on/off operation provides a direct method of disconnecting the battery supply in applications requiring controlled electrical isolation. The switch is ignition protected for use in engine compartments and supports both surface and panel mounting.

Performance Specifications

  • Continuous rating: DC 275 A
  • Intermittent rating: DC 455 A for 5 minutes
  • Cranking rating: DC 1,250 A for 10 seconds
  • Voltage rating: DC 48 V
  • Terminal studs: M10 (3/8 in.)
  • Housing material: Reinforced nylon

Safety Features and Certifications

  • Removable safety knob can be removed in the OFF position to help prevent accidental operation.
  • Ignition protected and meets ISO 8846 requirements for engine compartments.
  • Battery isolation supports safer storage and servicing by disconnecting battery power.

Installation and Maintenance Requirements

The battery switch supports surface or panel mounting. Installation uses the M10 (3/8 in.) terminal studs. Position the switch for accessible on/off operation and confirm that connected circuit loads remain within the applicable continuous, intermittent, and cranking ratings. The reinforced nylon housing supports routine use; maintenance consists of keeping the switch and terminals clean and checking connections during equipment service.
